ELECTRIC DROPLIGHT SHADE.

Application filed February 6, 1923. Serial No. 617,414.

T @ZZ whom t 'may concern.'

Be it known that I, HARRY P. SIMoNDs, a citizen of the United States, residing at Washington, in the District of Columbia,

have invented. certain new and useful Improvements in Electric Droplight Shades, of which the following is a specification.

My invention consists in a 4lamp shade with a longitudinal slot and is intended to be used on such lamp fixtures as will permit of such shade being placed thereon by means of said slot, such as the droplights in ccmmon use, and other lights mounted so the shade may be similar-ly applied. It relates chieiiy to electric drop lights such as have a cord with a socket at its vlower end for engagement with the electric bulb.

One object in view is to provide a shade of this character which may be easily placed upon the lamp or removed therefrom without disturbing` any of the parts of the lamp or having to change any of them relatively to each other. Another object is to provide a device of this character which can be easily adjusted on the lamp to throw the light to any desired part of the room while at the same time shading the rest of the room.

Speaking in general terms my invention consists of a vertically disposed semi-spherical shade having at its upper side a support adapted to be rotatably mounted on the electric light socket around the supporting cord, said support having a longitudinal slot in one side thereof leading into the centre of the support for the receptionthereinto of the drop light cord, said support also having transverse slots at opposite sides of the longitudinal slot and leading out therefrom to receive the stem of the turn-plug and to adapt the support to be rotated on the socket either toward the right or left Without contacting with said plug.

rIhe invention consists in the novel construction and arrangement of the several parts as hereinafter described and claimed reference being had to the accompanying drawings, in which Fig. 1 is a front View of a shade embodying my improvements. Fig. 2 is a side elevation, (partly broken away,) showing my improved shade in position on a drop cord, the lamp and cord being shown in dotted lines. Fig. 3 is a broken top plan view of a shade made in accordance with my invention. Fig. 4 is a plan view of the blank from which the body of my supporting member is formed; and Fig. 5 is a top` plan view of the supporting member before the saine is `secured to the shade proper.

The numeral 1 indicates a lamp shade or 60 reflector of well known form, usually made of metal. Attached to the shade at the upper side thereof is a supporting member A having a dome-shaped cover 2 rigidly secured thereon. This supporting memberis adapted to fitv over an electric lamp socket of the usual type used in connection with incandescent electric lamps. The domeshaped cover 2 has a central opening 2 and a slot 2b leading out therefrom through 70 the front side of the lid. The member A has in its front side a longitudinal slot l3 whichy yregisters with the slot 2b of the lid; and the margin of ythe shade proper has a cutaway segment Ll registering with the slot 3. Leading out transversely from the slot 3 on opposite sides thereof are the slots 5 for the reception of the turnplug K of the socket7 and to permit said supporting member 2 to rotate in either di- 80 rection on the socket without contacting with said turn plug.

In placing my improved shade in operative position on a lamp, the cord of the lamp just above the socket is passed laterally into the longitudinal slot 3 of the supporting member A till the hole 2a at the centre of the lid of said supporting member is reached. The supporting member is then moved downwardly and is rotated into position to permit the turn plug K to pass up through the cutaway portion l into position to be received into the transverse slots 5 whenthe shade is rotated around the cord. When this position is reached the dome-shaped cover 2 of the supporting member will be resting on the upper end of the turn-plug K upon which the slots 5 permit it to be rotated freely to cause the shade to face toward any desired part of the room, to flood that part with light while shading the rest of the room. And since the socket is now received into the supporting member A, the latter is safely held in operative position on the lamp, and though it may be freely rotated thereon, it cannot be removed therefrom till it is again elevated suciently to bring the vertical slot 4 above the turn plug.

The member A is preferably formed of a piece of sheet metal (as shown in Fig. zl) bent into the desired form with its domeshaped `cover 2 rigidly secured thereon in any desired manner, as for'inst-ance,`by soldering.

The blank 7 illustrated in Fig. 4 has its lower edge provided with a number of short spaced cuts forming teeth 8, as it were, on the edge of the member; and these teeth are shown in Fig. 5 asbeingtbent-outwardly at right angles to the main body of the member-to "iform a broken-liange'around the lower end thereof, whereby to provide a more convenient means for' rigidlyA securing the lower end of the member A to the shade, either by soldering or otherwise. Of course,

' the toothed flange' may be omitted if desired,

as the `two l.parts can be soldered `together without it.

Having now described my invention, what I claim'as new and desire to protect by :Letters Patent is ,In a lamp shadeor electric drop lights, a cup-'shaped member inverted to form the top of the `shade into a dome, said Emeinber beingadapted to'fit over an'electric bulb and havinga central opening for the reception of the drop-light cord, :said cup-shaped portion below the dome having ahorizontal slot extending outwardly from the centre of said portion through the side thereof, and a Vertical slot intersecting said horizontal slot at its centre and extending on inwardly lthrough the top of .the dome into the opening at the centre thereof, the vertical slot being yadapted for the passage o'f the cord laterally inward to the centre .of the shade support, and the horizontal slot being lspaced from the top of the dome a suitable distance to receive the turn-plug of the socket when the socket is in its lowermost position on the drop-light; whereby said holder may be placed on a cord over a drop-light `and may be rotated `freely thereon to face in different directions, the horizontal slot serving to 'form a path for the stem of the turn-plug when the shade is rotated on the cord in either direction, and yalso forming a lock for the shade on the socket to prevent upward movement of the shade thereupon, whichever lway it is turned.

In testimony whereof I atlix my signature.

HARRY 1P. SIMONDS.
